Letters Patent No. 104,804,114@ .mie. 2s, 1870.

To v-llwhom it may concern.' l Beit known that I, PETER L. Wnmnn, of Lebanon, 1n the county of Lebanon and State o'f Pennsylvania, have invented an Improved Tweer; and I do hereby declare that the following is a full, clear, and exactdescription thereof, reference being had tothe accompanying drawing making part of this specifica- .tion,'in which Figure lis a side elevationoi' the improved tweer. Figure 2 is an end view ofthe same. Figure 3 is a diametrical section throughthc tweer. Figure 4 is ,an end view, from which fig. '3 is projected.

Figure 5 cover.

Similar fletters of reference indicate corresponda g parts inthe several figures.

The object 'of this invention is- First, 'to construct a tweer with internal longitudipartitions, 'arranged in such relation to the inlet and outlet-orifices for water that a current of water is an end view of the tweer without the `can. .be caused to' circulate between the walls of the tweer, from one orifice to another, in -a continued nt being alternately. from one end to another of the tweer. l

Second,in constructing ot cast metal a. tweer which is only composed of two separatelyformed pieces, one.

and4 the other a double wall-partitioned body, as will lbe hereinafter explained.

To enable others skilled in the art-to understand my invention, I will-explain lits construction and' op eration.

In the accompanying drawing- A, A2, and P are portions constituting the nay improved double-wall-partitioned tweer.

v This body-portion ,is made 'of the usual well-known brm exteriorly, to wit: the form of the frustum of a hollow cone.' l V The oute'r wall'A, the inner wall A?, and thepartitions vI", are cast in one piece, with the partitioned space at the smallest endl closed, and-the correspondvbody of The twce'r shown in the drawing hasbut four pari titions in its water-circulating space, arranged at equal distances apart; fbut, if. desirable, a greater or even a lessernumber may be adopted.' A

These partitions are made in such manner that water entering through the pipe a w'ill circulate from one end to the other of each space included between two partitions, and then escape out of the pipe a. Consequently there can be no trapping or accumulation ot' steam at any part di' the tweer.

The cap-,ring Bis constructed with openings, a c', through it, and also with an annular tongue, c, which between the two Walls, A A, at the. butt or largest ring-cover B is secure y bolted to theA flanges, b', on rthe body-portion. f

I am awa-re that twecrs of the general form shown in the drawing have been made, .before my invention, of wrought metal, such as wrought irony and copper; but, owing to the want of proper directors or divisions in such tweer,s,.steam will form and accumulate in spaces which are out 'of the line of the currents ot' water. v

I am also, aware that a spiral coil of pipg, inclosed externally by a casing, has beeuused prior to my iuvention as a tweer. This form will obviate the objection above mentioned, but it isjliable to a still more serions objection, namely: the pipe-coil will soon.- be filled with incrustation. v '5 In using tweers, according to my invention, the head of water is usually frppi twenty-,tipe to' fifty fen'nd a stream of .water is conveyed ii'om -this height in -a pipe to theinlet-pipe of the tweer, when, after passing through the tweer, it is allowed a. free escape; but, when water is a' scarce article,- the escape-water of the tweer of a furnace is conveyed-to a large-coolhead-tank, to be used again. Furnace men generallythat the escaping stream isalways invieW, aud,by feeling the temperature of the escape-water, regulate the quantity flowing into the tweer. \Vith such' a. strong head of' water, necessaryto keep a suiiicient current of water going through the. tweer, Vit wasI found in the old plate-tweer that the current set from inlet to outlet-pipes by the most direct route, thus al-A steam, the consequence of which was a holejburned into the tweer. And it was for 'this reason that I, after manufacturing for nearly twelve years more than' one-haif of the twcers.made' in the; Uni p vised my improved tweer, which is, in all its parts, subjected to the direct actionof the water of circula,- tion, by reason ofthe alternate ow of thewater from ,nose to butt and butt to-nose, which is elected'pby the -longitudinal divisions of myitweer terminating alter` nately at nose and butt of the tweer, and leaving a sufficient space to allow a free passage of the water in a circuitous course. t s

I am aware of the French patentofUorlett, which,

half, the water being free to enter the lower, and' escape through the opening into the upper half',( by permitting it to obey the physical laws which make the warm particles of .this liquid to rise to the surface,

latter is adapted to t snugiy into the annular space end of the body of the tweer, as .shown in fig. 3. This.

ing-pond orreservoir, when it is pumped to the overhave tlie escape-water of their twers so arranged lowing parts of the tweer to be without circulation., In thcse parts the water was rapidly converted into ted States, de-

describes a tweer composed of au upper and' lower, l

and thence into the forebay or reservoir, to repeat the same process; but my tweer diers from his iu essential particulars, besides being eastin one piece-an advantage, not of manufacture, but of practical benelit in the use of the tweer.

I therefore disclaim the inventionV described in snid patent to Gorlett, and

I claim the improved tweer herein described, com posed of the chamber-walls A A and partitions 1L cast; in one piece, and so that, when the head or butt B, 'with inlet' 'and outlet-passages in it', is applied, 'che tweer will be complete, and there will alternately be at the nose and butt of the tweer, .within lche walls A A, a. passage for the circulation of the water through every parl: of the chamber, substantially in the manner described.
